Barry, You might consider using a "real" database. ;-)
Seriously though, Access is pretty bad and only suitable for very small, low performance apps. Interbase is only marginally better. MySQL, another DB engine, is free and there are some great Delphi components for it. Check out the ZeosLib components - they are free, open source and in active development. You can download the community version of MySQL from their web site. Installation is pretty easy, and there are lots of books about it at the bookstore. MySQL can support ~100 simultaneous users and can be used over the Internet. I use MySQL and Zeoslib components in all my DB applications that run at large companies. In answer to your original question, you probably want to use BLOB records to store the binary portion of the image, and save the image type in another field of the DB. As you load a record, you'll have to pass the BLOB to the appropriate image viewer, based on your image type field contents. DevExpress has a TcxDBImage component that supports BMP, ICO, JPG, and PNG, or you could do something clever with streams and some other cheaper image component. DevExpress is expensive, but worth it. There may be other components that will get the job done - maybe someone else can chime in here. HTH! Kevin G.
